While INSIDER could not independently confirm that the Reddit user, busty_chemist, did indeed go to school with Plaza, they did describe their interpretation of Plaza's childhood personality in the thread.

"She wasn't deadpan or sarcastic when I knew her (I think that's just something kids don't have, maybe) but she definitely had a quirky sense of humor. She was also totally un-self-conscious in a way I envied," they wrote. "If anything I'm only surprised that she's not a bigger star than she is."

"Not really surprised. She always loved attention (not in a bad way) and was definitely a performer," they wrote, adding that it "helps" that Plaza came from a wealthy family. "But she was a lovely girl. She deserves the success."

A representative for Plaza did not immediately return INSIDER's request for comment.
